Study on the Structure, Thermodynamic property, and Fluorescence of Pyridin‐2‐ylmethyl‐tert‐butylamine Dimethyl aluminum complex

In this investigation, Schiff bases aluminum complex was synthesized and used as the initiator in the polymerization of D,L-lactide. The aluminum complex was characterized by infrared spectroscopy (IR), and nuclear magnetic resonance spectroscopy (NMR). The influences of different factors, including reaction time, reaction temperature, and the ratio of D, L-lactide/Al3+ on the synthesis of polylactide were described. The results showed that Schiff bases aluminum complex could be successfully applied in the ring opening polymerization. The optimum condition of the ring opening polymerization of D,L-lactide, which included D,L-lactide/Al3+ (mol/mol) ratio of 250, reaction temperature of 120 °C, and reaction time of 16 hours.

Electron Transport Properties

We report the synthesis, photophysical investigation, computational studies and electroluminescent(EL) properties of an organic electroluminescent material-Bis(8-hydroxyQuino line) acetylacetone aluminum (Alq2A). It is characterized by 1H NMR, IR and elemental analysis techniques. The absorption and fluorescence spectra of various Alq2A systems including solution in ethanol, powder and thin film on quartz (thickness of 50nm) have also been systematically evaluated. Analysis of the electronic structure of Alq2A calculated by quantum chemical calculations reveals a localization of orbital and the distribution of orbital energy. The results from EL experiments indicate that Alq2A has good electron transport properties as compared with tris(8-hydroxyquinolinato) aluminum (Alq3). Thus, Alq2A is considered to be a superior emitter and electron transporting material for display application compared with Alq3.
