A series of dipolar and octupolar triphenylamine-derived dyes containing a benzothiazole positioned in the matched or mismatched fashion have been designed and synthesized via palladium-catalyzed Sonogashira cross-coupling reactions. Linear and nonlinear optical properties of the designed molecules were tuned by an additional electron-withdrawing group (EWG) and by changing the relative positions of the donor and acceptor substituents on the heterocyclic ring. This allowed us to examine the effect of positional isomerism and extend the structure-property relationships useful in the engineering of novel heteroaromatic-based systems with enhanced two-photon absorption (TPA). The TPA cross-sections (deltaTPA) in the target compounds dramatically increased with the branching of the triphenylamine core and with the strength of the auxiliary acceptor. In addition, a change from the commonly used polarity in push-pull benzothiazoles to a reverse one has been revealed as a particularly useful strategy (regioisomeric control) for enhancing TPA cross-sections and shifting the absorption and emission maxima to longer wavelengths. The maximum TPA cross-sections of the star-shaped three-branched triphenylamines are ?500-2300 GM in the near-infrared region (740-810 nm); thereby the molecular weight normalized deltaTPA/MW values of the best performing dyes within the series (2.0-2.4 GM?g-1?mol) are comparable to those of the most efficient TPA chromophores reported to date. The large TPA cross-sections combined with high emission quantum yields and large Stokes shifts make these compounds excellent candidates for various TPA applications, including two-photon fluorescence microscopy.

A tunable route to both isomers of benzo[d]imidazothiazole has been developed through copper-promoted cycloaddition of alpha-methylenyl isocyanides with benzothiazoles. When the C2 position of benzothiazole is linked to a C-H or C-C bond, benzo[d]imidazo[2,1-b]thiazoles are obtained through a novel rearrangement via C-S bond cleavage and formation of a new C-S bond. When 2-chloro- or 2-bromobenzothiazoles are used under the same reaction conditions, the isomeric benzo[d]imidazo[5,1-b]thiazoles are formed selectively. These reactions proceed smoothly in moderate to excellent yields at room temperature, and a wide range of functional groups are tolerated.

A synthesis of the halogeno derivatives of substituted benzothiazoles (2-6) is described, and dimerization using copper in different oxidation states is examined. Dimerization of iododerivatives (2) and (4) by copper(I) thiophen-2-carboxylate (CuTC) mediated coupling afforded the corresponding o,o’-disubstituted bibenzothiazoles (7) and (S) in excellent yield.{A figure is presented}.
