标题:Methods and compositions for synthesis of two-photon cleavable phosphoramidite molecules for oligonucleotide conjugation
发明人：LO PEGGY PIK KWAN; LIU LING SUM; TAM DICK YAN
权利人:UNIV CITY HONG KONG
摘要:The syntheses of two phosphoramidite building blocks based on BNSF and BNSMB structures are disclosed. Furthermore, some common molecular intermediates have been designed and linked to the central biphenyl core of the two molecules, resulting in a versatile and cost-effective design. These compounds can be effectively introduced to DNA oligonucleotides via the well-established standard cyanoethylphosphoramidite chemistry on the nucleic acid synthesizer. Fragmentation of these BNSF- and BNSMB-functionalized DNA strands is achieved by both one-photon and two-photon photolysis of photoliable bonds of [2-(2-nitrophenyl)propoxy]carbonyl groups on BNSF and BNSMB molecules respectively, resulting in two short pieces of single-stranded DNAs. The versatile design and facile synthesis of these two-photon photocleavage phosphoramidite molecules are beneficial to synthetic chemists and photochemists for the development of new caged compounds which enables to introduce into oligonucleotides as light-triggered carriers via solid-phase synthesis for a wide range of applications in materials science, polymer, chemistry, biology and DNA nanoecthnology.

权利人:USA FORTESCUE IP INC
摘要:An ion exchange polymer has an ionomer structure containing poly(phenylene) compound integrated with functionalized poly(fluorene). The ion conducting co-polymer includes a poly(fluorene) compound and a poly(phenylene) compound covalently bonded together. The poly(fluorene) compound has a 9H-fluorene structure that is a polycyclic aromatic hydrocarbon having a center ring with five carbon atoms, and a benzene ring on each of opposing sides of said center ring. The poly(phenylene) compound is covalently bonded to each of the pair of benzene rings of the poly(fluorene) compound. A pair of sidechains extends from the center ring of the poly(fluorene) compound to a respective terminal group. The terminal groups are configured on sidechains of the poly(fluorene) compound and can be converted into functional groups such as quaternary ammonium or n-methyl piperidine functional groups. The ion exchange polymer may include a porous scaffold support.

摘要:A method of synthesizing a two-photon active tris(diarylamino-9,9-di(R)fluorenyl)-1,3,5-triazine compound having the structure: n nwhere Y is hydrogen, a thermally self-polymerizable acrylic, or a methacrylic group; R is an alkyl group of the formula —C m H 2m+1 , wherein the subscript m ranges from 1 to 6, or an alkylether group of the formula —(CH 2 CH 2 O) p Me, wherein the subscript p ranges from 1 to 5; R′ is an alkyl group; and the R′—(OY) x groups are attached to the phenyl rings of the triarylamine moiety either in a para position or a meta position and the subscript x ranges from 1 to 3. The compound may be synthesized by (a) synthesizing a diarylamine intermediate, (b) synthesizing a brominated 1,3,5-triazine intermediate as a three-arm core structure, and (c) forming the two-photon active tris(diarylamino-9,9-di(R)fluorenyl)-1,3,5-triazine compound by covalently joining the diarylamine and each arm of the three-arm core structure and removing the acetone protecting groups. The diarylamine intermediate may be synthesized by protecting tris-1,1,1-(hydroxymethyl)ethane, via a ketal formation with acetone, as an acetonide derivative; furnishing bromophenoxy-methyltrimethyl-1,3-dioxane from the acetonide derivative; and arylating aniline with the bromophenoxy-methyltrimethyl-1,3-dioxane.

摘要:Polymer transport materials for application in perovskite solar cells capable of being tuned or manipulated to achieve desired properties, are provided herein. The present disclosure is directed to methods, systems, and compositions for achieving polymer transport materials (i.e., hole transport materials (HTMs)) with desirable properties such as solution processability, energy level tuning (i.e., adjusting), high thermal properties, tunable (i.e., adjustable) wettability, and perovskite defect passivation. In some aspects of the present disclosure, the synthesis of such HTMs may be implemented via relatively simple and inexpensive processes.
