Spectroscopic and electrochemical study of a novel blue electroluminescent p-n diblock conjugated copolymer

Article Abstract:

A new p-n diblock conjugated copolymer composed of N-(2'-thyl hexyl)carbazole and 1,4-bis(1,3,4-oxadiazole-2yl)-2,5-dioctyloxybenzene segments was synthesized and characterized. The UV-vis and photoluminescence spectra revealed that the polymer emits is a greenish-blue light. Cyclic voltammetry examination showed that the highest occupied molecular orbitals (MOs) and lowest unoccupied MOs of the polymer were adjusted by combining the oxadiazole moiety and the carbazole segment. The combination can improve the imbalanced hole-electron injection/transporting ability of most conjugated copolymers.

Dynamics, particle interactions, and network formation

Article Abstract:

Issues concerning the dynamic properties of microemulsions in the L2-phase with EO13PO30EO13 as stabilizer and p-xylene as oil are discussed. Temperature and water content have a strong effect on the microemulsion properties.
