Title: Dry Etching of Metal Phthalocyanine Films: Effects on Morphology and Surface Stoichiometry
Authors: Jaron G. Van Dijken 1 and Michael J. Brett 1,2

Abstract: We investigate the evolution of metal phthalocyanine thin films as they are etched with argon plasma. Significant morphological changes occur as a result of the ion bombardment; a planar surface quickly becomes an array of nanopillars which are less than 20 nm in diameter. The changes in morphology are independent of RF power, which controls the etch rate only. Analysis with XPS shows that surface concentrations of copper and oxygen increase with etch time, while carbon and nitrogen are depleted. Despite these changes in surface stoichiometry, we observe no effect on the work function. The UV/Vis and FTIR absorbance profiles, as well as XRD patterns, show no changes other than the peaks diminishing with etch time. These findings have important implications for the accuracy of various depth profiling techniques employing sputtering (AES/SIMS/XPS) as well as for organic photovoltaic devices which seek highly columnar thin films of MPc materials.

Title: Porphyrin Magic Strikes Again: Act as Index Chemicals for Developing Dual-functional Phototherapy and Biomedical Imaging Probes

Abstract: Porphyrins are naturally selected for life to fulfill exquisite works, such as transporting oxygen and transferring electrons, which are wildly applicable to chemistry, physics, materials, engineering as well as biology and medicine. Novel porphyrin-based bifunctional agents for biomedical imaging and photodynamic therapy have been recently explored, especially with two-photon absorption (in near infra-red region which is tissue transparent) molecules with higher triplet states, singlet oxygen quantum yields, TPA cross-section σ2 and rapid cellular uptake properties, but low dark cytotoxicities. Herein, we review the recent advance of porphyrin-based photosensitizers and their applications on phototherapy and imaging. Rational structural designs, appropriate selection of chain radicals and complexation center molecules, as well as biomedical applications are elucidated. The photophysical properties (linear and two-photon absorption) porphyrins conjugated to transition metal and also lanthanide centers are especially addressed.

Title: Tetrapyrrolic Macrocycles as Contrast Agents for Molecular Imaging: An Overview

Abstract: The field of imaging science is growing immensely, with the emergence of “noninvasive” in vivo imaging technologies and imaging probes like PET and 19F- MRI, to observe events at molecular and cellular levels, and consequently to speed up drug development processes. For instance, the imaging of cancer specific molecular targets ought to permit precocious diagnosis and superior evaluation to oncology patients. Porphyrin and its derivatives (or related compounds, like phthalocyanines) represent one of the oldest, most widely studied chemical structures, both in nature and in biomedical applications. They display intrinsic affinity for tumor localization and their well-portrayed photophysical and photosensitizing properties can lead to their potential use as sensitizer in a variety of in vivo imaging technologies. This contribution will review recent developments involving tetrapyrrolic –based sensitizers for cancer detection and treatment, with emphasis on PET and 19F- MRI technologies. Looking forward to hearing from you.
