Photosensitive polymer hybrids with poly(acrylic acid) (PAA) could be obtained by using caged (photosensitive protecting group modified) alkoxysilane (NVOC-U-PTEOS). Transparent polymer hybrids were prepared with UV irradiation, while the obtained materia

To accomplish high photosensitivity of resist systems including photobase generators, we have proposed the concept of base-proliferation reactions that generate base molecules in a nonlinear manner by the action of a catalytic amount of base; however, exc

The possibility of wavelength-selective cleavage of seven photolabile caging groups from different families has been studied. Amine-, thiol-, and carboxylic-terminated organosilanes were caged with o-nitrobenzyl (NVOC, NPPOC), benzoin (BNZ), (coumarin-4-yl)methyl (DEACM), 7-nitroindoline (DNI, BNI), and p-hydroxyphenacyl (pHP) derivatives. Caged surfaces modified with the different chromophores were prepared, and their photosensitivity at selected wavelengths was quantified. Different pairs, trios, and quartets of chromophore combinations with wavelength-selective photoresponse were identified. Our results show, for the first time, the possibility of generating surfaces with up to four different and independently addressable functional levels. In addition, this manuscript presents the first systematic comparison of the photolytic properties of different photolabile groups under different irradiation conditions.(Figure Presented)
