The synthesis of novel luminescent polymer containing p-phenylene-ethynylene and 9,12-linked o-carborane units alternately in the main chain is reported. The obtained polymer exhibits intense blue photoluminescence, providing the first insights into the optical properties of a 9,12-disubstitutedo-carborane dye. -Conjugated substituent at 9 and/or 12-positions ino-carborane is electrically independent, and both the HOMO and the LUMO levels slightly increase, whereas LUMO of the -conjugated substituent at 1 and/or 2-positions in o-carborane decrease.Thus, it is deduced that polymers consisting of the 9,12-linkedo-carborane unit are able to be applied as light-emitting materials.
