Title
A novel way to prepare luminescent hybrid materials derived from 5-chloromehtyl-8-hydroxyquinoline and silylated monomer with coordination to aluminum ion
Abstract

In this article, a new method to synthesize novel metaloquinolate-contained electroluminescent hybrid materials is reported. The small molecule metal complex monomer was obtained from the reaction of 3-piperazinepropylmethyldimethoxysilane and 5-chloromethyl-8-quinolinol hydrochloride. Then the silylated metaloquinolate-contained monomer was complexed with aluminum ion and further introduced into silica matrices by Si–O bonds and formed hybrid materials after hydrolysis and polycondensation processes. FT–IR, UV, NMR, SEM, TGA, luminescence spectra and luminescence quantum yields were used to characterize the obtained hybrid materials. It was found from the scanning electron micrographs (SEM) results that no phase separation occurred in 8-hydroxyquinoline aluminum complexes-silicone hybrid materials. The target materials were thermally stable until 380 °C and exhibited high quantum yield (43%). Such materials should combine the fluorescent properties of metalloquinolate and good mechanical properties, stability, and processability of organosilicone to improve device efficiencies and work lifetimes, and should be of interest for OLED applications.
