Publication number: 20220088226Abstract: Fluorescent nucleobase surrogates capable of Watson-Crick hydrogen bonding are essential probes of nucleic acid structure and dynamics. Their limited brightness and short absorption and emission wavelengths have rendered them unsuitable for single-molecule detection. Herein, we synthesized a new tricyclic pyrimidine nucleoside analogue with a push-pull conjugated system. The resulting C-linked 8-(diethylamino)benzo[b][1,8] naphthyridin-2(1H)-one nucleoside (ABN), exhibits ?442=20,000 M?1 cm?1 and ?em,540=0.39 in water, increasing to ?em=0.50-0.53 when base paired with adenine in duplex DNA oligonucleotides. Single-molecule fluorescence measurements of ABN using both one-photon and two-photon excitation demonstrate its excellent photostability and indicate that the nucleoside is present to >95% in a bright state with count rates of at least 15 kHz per molecule.Type: ApplicationFiled: September 16, 2021Publication date: March 24, 2022Applicant: San Diego State University FoundationInventors: Byron W.

Publication number: 20210402380Abstract: Nature is capable of storing solar energy in chemical bonds via photosynthesis through a series of C—C, C—O and C—N bond-forming reactions starting from CO2 and light. Direct capture of solar energy for organic synthesis is a promising approach. Lead (Pb)-halide perovskite solar cells reach 24.2% power conversion efficiency, rendering perovskite a unique type material for solar energy capture. We show that photophysical properties of perovskites is useful in photoredox organic synthesis. Because the key aspects of these two applications are both relying on charge separation and transfer. Here we demonstrated that perovskites nanocrystals are exceptional candidates as photocatalysts for fundamental organic reactions, i.e. C—C, C—N and C—O bond-formations. Stability of CsPbBr3 in organic solvents and ease-of-tuning their bandedges garner perovskite a wider scope of organic substrate activations.Type: ApplicationFiled: June 17, 2021Publication date: December 30, 2021Applicant: San Diego State University FoundationInventor: Yong YAN
