DHNT MONOMERS AND POLYMER DYES WITH MODIFIED PHOTOPHYSICAL PROPERTIES
摘要:
The present disclosure relates to dihydronaphthothiophene (DHNT), dihydrobenzodithiophene (DHBDT), and dihydronapthothienothiophene (DHNTT) monomer units and fluorescent polymers and co-polymers thereof. DHNT, DHNTT, and/or DHBDT containing water-soluble fluorescent co-polymers, water-soluble tandem fluorescent co-polymers, water-soluble fluorescent co-polymer complexes, water-soluble tandem fluorescent co-polymer complexes, and their use in methods for detecting analytes in a biological sample are also provided.

controllable and synthetically useful base‐promoted intramolecular detosylative cyclization of bis‐N‐tosylhydrazones has been achieved, affording N‐containing heterocycles and cyclic olefins under transition‐metal‐free or gold‐catalyzed procedures, respectively. Moreover, an effective and practical metal‐free or gold‐catalyzed approach to synthesize polycyclic aromatic compounds is also reported.
catalyst for the directarylation of 3-substituted thiophene derivatives. The regioselectivity of the arylation strongly depends on the thiophene substituent and also on the nature of the arylbromide. When using 3-formyl, 3-cyano, 3-methyl, 3-hydroxymethyl or 3-bromothiophene, the 2-arylated thiophenes were obtained with 76-95% regioselectivity; whereas, the arylation of 3-formylthiophene diethylacetal

The system Pd(OAc) 2 /dppb was found to be an efficient catalyst precursor for the directarylation of 3-formylthiophenederivatives. When using 3-formylthiophene, the 2-arylated thiophenes were obtained with regioselectivities of 76―86 %, whereas the arylation of 3-formylthiophene diethyl acetal gave the 5-arylated thiophenes with regioselectivities of 64― 88 %. These reactions were performed by using

Ahead of the PAC: Polycyclicaromaticcompounds (PACs) can be easily accessed by the combination of Suzuki–Miyaura cross‐coupling and a [Rh2(OAc)4]‐catalyzed carbene reaction using easily available bis(N‐tosylhydrazone)s as intermediates (see scheme; Ts=4‐toluenesulfonyl).
