Special Issue Information

Dear Colleagues,

The combination of mobility and order in liquid crystals allows them to respond to a variety of external stimuli, and this is undoubtedly an inspiring feature for the design of smart materials. In the last few years, liquid crystals have emerged as a vehicle to control the organization of matter, from the micro- to the nanoscale, through the exploitation of mesogenic driving forces to self-organize molecules into defined arrangements. As a matter of fact, the diversity of liquid crystals, calamitic, discotic, bent-core or lyotropic mesophases, and their special responses to light, temperature, electric field, magnetic field or mechanical stress, among others, provide a myriad of opportunities in the field of functional materials. Both attributes, organization and responsiveness, situate liquid crystalline materials at the forefront of the investigation and progress of those materials that rely on a well-organized internal structure to display advanced functional properties.

Nowadays, optoelectronics, membranes or nanoparticles are employing mesophases as arranging media for the preparation of innovative materials with tuneable properties. Additionally, liquid crystalline materials endowed with photoactive abilities have arisen as very appealing and multi-stimuli responsive systems and actuators. In addition to this, processing materials through mesophases yields high performance materials and devices.

With this Special Issue, we aim to highlight some new stimulating reports on liquid crystals paving the way toward advanced functional materials, focussing from fundamental aspects through applications and future perspectives. We would like to take this opportunity to invite contributions from experts working on the design, synthesis, preparation, characterization or application of functional materials that have identified and selected liquid crystals as a smart and elegant working tool for their purposes, welcoming both original research papers, as well as review articles.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1500 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Organic solid-state tri-wavelength lasing was demonstrated from dye-doped holographic polymer-dispersed liquid crystal (HPDLC) distributed feedback (DFB) laser with semiconducting polymer poly[-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene-vinylene] (MEH-PPV) and laser dye [4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran] (DCM) by a one-step holography technique, which centered at 605.5 nm, 611.9 nm, and 671.1 nm.

Organic solid-state tri-wavelength lasing was demonstrated from dye-doped holographic polymer-dispersed liquid crystal (HPDLC) distributed feedback (DFB) laser with semiconducting polymer poly[-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene-vinylene] (MEH-PPV) and laser dye [4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran] (DCM) by a one-step holography technique, which centered at 605.5 nm, 611.9 nm, and 671.1 nm. The temperature-dependence tuning range for the tri-wavelength dye-doped HPDLC DFB laser was as high as 8 nm. The lasing emission from the 9th order HPDLC DFB laser with MEH-PPV as active medium was also investigated, which showed excellent s-polarization characterization. The diffraction order is 9th and 8th for the dual-wavelength lasing with DCM as the active medium. The results of this work provide a method for constructing the compact and cost-effective all solid-state smart laser systems, which may find application in scientific and applied research where multi-wavelength radiation is required.
