Usage

General Description

4-(10-Phenylanthracen-9-yl)phenylboronic Acid Pinacol Ester is a versatile chemical compound that belongs to the class of boronic acids and esters. These types of compounds are essential in the field of organic chemistry, particularly in Suzuki-Miyaura cross-coupling reactions, because of their remarkable ability to form carbon-carbon bonds. Additionally, this chemical, due to the presence of a Phenylanthracene compound, has strong fluorescence properties, making it relevant for use in optical materials such as organic light-emitting diodes (OLEDs). It's also noteworthy that the pinacol ester group in the compound enhances the stability of the boronic acid, facilitating a more profound chemical interaction.

Evolution from Tunneling to Hopping Mediated Triplet Energy Transfer from Quantum Dots to Molecules

Efficient energy transfer is particularly important for multiexcitonic processes like singlet fission and photon upconversion. Observation of the transition from short-range tunneling to long-range hopping during triplet exciton transfer from CdSe nanocrystals to anthracene is reported here. This is firmly supported by steady-state photon upconversion measurements, a direct proxy for the efficiency of triplet energy transfer (TET), as well as transient absorption measurements. When phenylene bridges are initially inserted between a CdSe nanocrystal donor and anthracene acceptor, the rate of TET decreases exponentially, commensurate with a decrease in the photon upconversion quantum efficiency from 11.6% to 4.51% to 0.284%, as expected from a tunneling mechanism. However, as the rigid bridge is increased in length to 4 and 5 phenylene units, photon upconversion quantum efficiencies increase again to 0.468% and 0.413%, 1.5-1.6 fold higher than that with 3 phenylene units (using the convention where the maximum upconversion quantum efficiency is 100%). This suggests a transition from exciton tunneling to hopping, resulting in relatively efficient and distance-independent TET beyond the traditional 1 nm Dexter distance. Transient absorption spectroscopy is used to confirm triplet energy transfer from CdSe to transmitter, and the formation of a bridge triplet state as an intermediate for the hopping mechanism. This first observation of the tunneling-to-hopping transition for long-range triplet energy transfer between nanocrystal light absorbers and molecular acceptors suggests that these hybrid materials should further be explored in the context of artificial photosynthesis.

Excimer-emitting single molecules with stacked π-conjugated groups covalently linked at the 1,8-positions of naphthalene for highly efficient blue and green OLEDs

Two efficient blue-light-emitting compounds, 1,8-bis(4-(N-carbazolyl) phenyl)naphthalene (BCzPN) and 1,8-bis(4-(10-phenylanthracen-9-yl)-phenyl) naphthalene (BPAPN), are designed and synthesized, in which two phenylcarbazole or diphenylanthracene units are closely stacked through bonding to the 1- and 8-positions of the naphthalene ring, resulting in strong intramolecular excimer emissions in solution or as a film. By utilizing BPAPN as an emitter, high efficiencies of 6 cd A-1 and 5.8% external quantum efficiency (EQE) at 100 cd m-2, and 8 cd A-1 and 5.8% EQE at 1000 cd m -2 are achieved in a non-doped blue device. By using BCzPN or BPAPN as a host, a DPAVBi-doped BCzPN based blue device gave high efficiencies of 15 cd A-1 and 6.5% EQE at 100 cd m-2, and 12 cd A -1 and 5.5% EQE at 1000 cd m-1, and a C545T-doped BPAPN based green device gave high efficiencies of 23 cd A-1 and 6.7% EQE at 100 cd m-2, and 22 cd A-1 and 6.7% EQE at 1000 cd m-2, respectively.
