| Research Abstract |
We have investigated on the developments of new family of pi-conjugated polymers containing silole (silacyclopentadiene)as a new building unit. Target molecules in this research are poly (2,5-silole) as well as copolymers of silole with thiophene, pyrrole, pyridine, benzene, and acetylene pi-electronic systems. Several types of silole-based pi-conjugated compounds have been prepared and their photophysical and electrochemical properties have been determined. Application to organic electroluminescent devices have also been examined. The results attained in this project are summarized as follows.
1.Synthesis and Properties of Silole-Pyrrole Cooligomers
2.Developments of Silole-Acetylene pi-Electronic Systems
3.Synthesis, Structures, and Properties of 2,5-Dithienyl Group 14 Metalloles : Effects of the Central Group 14 Elements on their Properties
4.New Synthetic Methods of Siloles 1 : Synthesis of 3,4-Unsubstituted Silole Derivatives via Tellurophenes
5.New Synthetic Methods of Siloles 2 : Synthesis of 2,5-Difunctionalized Siloles
6.Synthesis and Properties of 2,5-Diarylsiloles
7.Application of 2,5-Diarylsiloles to Organic Electroluminescent Devices
8.Preparation of Silole-Arene 1 : 1 Alternating Copolymers using Silole-2,5-diboronic Acids as Key Precursors
9.New Synthetic Route to 1,1-Difunctionalized Siloles
10.Silicon-Catenated Silole Oligomers : Oligo (1,1-silole)s
11.Synthesis of Poly (1,1-silole)s and Silole Cyclic Hexamer
