Synthesis and spectroscopic properties of a hexapyrenylbenzene derivative

(Chemical Equation Presented) In this paper, we present a synthetic approach to the first hexapyrenylbenzene starting from 4,5,9,10- tetrahydropyrene. Absorption and fluorescence spectroscopic measurements show strong and red-shifted fluorescence both from locally excited pyrene states and from the excitonic manifold of the aggregate.

A tetrahydropyrene-based organic dye for solar cell application

A novel tetrahydropyrene-based D-π-A organic dye D2 was designed and synthesized for the first time, featuring 4,5,9,10-tetrahydropyrene as a π conjugation linker to bridge the diphenylamine unit and the thienyl acrylic acid moiety. Its counterpart D1 was prepared for comparison, where biphenyl was used as the linker. Both dyes were characterized by photophysical, electrochemical, and theoretical computational methods. It was found that the introduction of two ethylene groups on the C2, C2′ and C6, C6′ of the biphenyl in D2 can prevent the rotation of the adjacent phenyl rings, and ensure the coplanarity of the bridge. As a result, the maximum absorption peak (λmax) of D2 was 29 nm red shifted as compared with D1. Nanocrystalline TiO2-based dye-sensitized solar cells were fabricated using the dyes as light harvesting sensitizers, and exhibited power conversion efficiencies of 6.75% for D2 and 4.73% for D1 under AM 1.5 conditions.

ARYL AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENCE DEVICE USING THE SAME

Disclosed are a novel aryl amine derivative and an organic electroluminescent device using the same. More specially, the aryl amine derivative is a compound comprising a tetrahydropyrene core, amine groups (-NAr1Ar2 and -NAr3Ar4) each independently substituted at 2 and 7 positions of the tetrahydropyrene, and aromatic ring groups (X1 and X2) each independently substituted or unsubstituted between the tetrahydropyrene core and the amine groups (-NAr1Ar2 and -NAr3Ar4). Further, provided is an organic electroluminescent device comprising (i) an anode, (ii) a cathode, and (iii) one or more organic layers between the anode and the cathode, at least one of the one or more organic layers comprising the aryl amine derivative. Preferably, the organic layer comprising the aryl amine derivative is a hole transport layer.
