Effects of Substituents in Polyvinylcarbazole Structures on Their Optical Properties

TL;DR

This study investigates how different substituents in polyvinylcarbazole structures affect their optical properties, including absorption and photoluminescence, in solutions and thin films, with implications for developing photosensitive polymer composites.

Contribution

It provides a comprehensive analysis of the optical spectra of various substituted polyvinylcarbazole polymers and copolymers, expanding understanding of their potential in photonic applications.

Findings

Substituents significantly influence absorption and emission spectra.

Polymers with specific substituents show enhanced photosensitivity.

Results support development of broad-spectrum photosensitive polymer composites.

Abstract

Absorption, photoluminescence, and photoluminescence excitation spectra of solutions and thin films of N-vinylcarbazole polymers and copolymers with various substituents directly on the carbazole moiety and on the polymer chain were studied comprehensively. Polymers that were used previously to develop polymer composites with polymethine dyes having photosensitivity over a broad spectral range including the visible and near-IR regions were selected for the studies.
