Trimethylsilyl o-xylenyl-substituted fullerene bis-adduct as electron acceptor for solution-processed polymer solar cells

A new trimethylsilyl o-xylenyl-substituted fullerene bis-adduct (TMS-OXCBA) was synthesized as an electron acceptor for solution-processed polymer solar cells (PSCs) via a Diels-Alder reaction. The Stern-Volmer quenching constant (Ksv) for the device containing poly(3-hexylthiophene) (P3HT) as the fluorophore and TMS-OXCBA as the quencher was 8.51 × 103 M-1, which correlated with the binding affinity of P3HT and TMS-OXCBA. The measured lowest unoccupied molecular orbital (LUMO) energy level of TMS-OXCBA was -3.53 eV and the electron mobility value obtained for the P3HT:TMS-OXCBA blend film was 1.94 × 10-4 cm2 V-1 S-1. Photovoltaic devices were fabricated using P3HT as the electron donor and TMS-OXCBA as the electron acceptor. The highest power conversion efficiency (PCE) value observed for P3HT:TMS-OXCBA was 2.53% with an open-circuit voltage (Voc) of 0.84 V, a short-circuit current density (Jsc) of 7.22 mA cm-2, and a fill factor (FF) of 0.42 under AM 1.5G illumination of 100 mW cm-2.

Rhodium N-heterocyclic carbene-catalyzed [4 + 2] and [5 + 2] cycloaddition reactions

A rhodium complex of N-heterocyclic carbene (NHC) has been developed for intra- and intermolecular [4 + 2] and intramolecular [5 + 2] cycloaddition reactions. This is the first use of a transition-metal NHC complex in a Diels-Alder-type reaction. For the

An Unprecedented Electronic Preference for the "Meta" Product in Diels-Alder Reactions of Ethynyldialkylboranes. -9-BBN as a Reactive and Versatile Dienophile

-9-BBN undergoes Diels-Alder reactions with acyclic dienes at 100 deg C to afford 1,4-cyclohexadienes in high yields.The novel regiochemistry of these reactions is consistent with an ab initio prediction of advanced bonding to boron in a transition state.
