摘要
Photo-reaction by UV irradiation of a highly fluorescent s-triazine bridged p-phenylenevinylene polymer resulted in micro and submicron fluorescent pattern because carbonyl group (C=O) was generated from vinylene group (C=C) through the photo-oxidation. This fluorescent pattern could be used for micro scale cell patterning as well as submicron scale biomolecules patterning such as proteins. When exposed to a solution containing biomolecules, the polymeric patterns were selectively coated with biomoleucles, to result in biomolecular patterns. In particular, the UV exposed area of the poly[4,6-bis(phenoxy)-2-diphenylamino-s-triazine]co(2,5-bis(trimethylsilyl)-1,4-phenylenevinylene) (DTSPV) patterns was highly selective toward fluorescein isothiocyanate (FITC) conjugated collagen. These studies provide an exciting opportunity for tissue engineering and fundamental understanding of the mechanisms of cellular adhesion, proliferation, and differentiation.
