Photo-functional infinite coordinated polymers (ICPs) were synthesized that consist of the photochromic dithienylethene (DTE) and a luminescent bridging unit to give enhanced fluorescence in the solid state. We could fabricate well-ordered micropatterns of these ICPs by a soft-lithographic method, which repeatedly showed high contrast on–off fluorescence switching.

Two light-driven chiral fluorescent molecular switches, (R,S,R)-switch 1 and (R,S,R)-switch 2, are prepared by means of hydrogen-bonded (H-bonded) assembly of a photoresponsive (S) chiral fluorescent molecule, respectively with a cyano substitution at different positions as an H-bond acceptor and an opposite (R) chiral molecule as an H-bond donor. The resulting two switches exhibit tunable and reversible Z/E photoisomerization irradiated with 450 nm blue and 365 nm UV light. When doped into an achiral liquid crystal, both switches are found to be able to form a CPL tunable luminescent helical superstructure. In contrast to the tunable CPL characteristics of the system incorporating switch 2, exposure of the system incorporating switch 1 to 365 nm and 450 nm radiation can lead to controllable different photostationary CPL behavior, including switching-off and polarization inversion. In addition, optical information coding is demonstrated using the system containing switch 1.

To develop next generation antifolates for the treatment of trimethoprim-resistant bacteria, synthetic methods were needed to prepare a diverse array of 3-aryl-propynes with various substitutions at the propargyl position. A direct route was sought whereb
Facile, Regioselective Synthesis of Highly Solvatochromic Thiophene-Spaced N-Alkylpyridinium Dicyanomethanides for Second-Harmonic Generation
Abbotto, Alessandro,Bradamante, Silvia,Facchetti, Antonio,Pagani, Giorgio A.
, p. 5755 - 5765 (2007/10/03)
The facile and clean synthesis of a novel class of highly solvatochromic chromophores 1 is reported. Compounds 1 are push-pull systems containing a negatively charged dicyanomethanide as a donor group and a positively charged N-alkylpyridinium as an acceptor group. The terminal polar functions are spaced by a thiophene-based moiety containing one or two heterocyclic rings and none, one, or two ethylene bridges. Chromophores 1 have been obtained through a general synthetic scheme involving, as the last step, the 100% regioselective alkylation of the precursor bidentate anions 2, where two competing nucleophilic sites, one neutral at the pyridic nitrogen and one anionic at the carbanionic carbon of the dicyanomethanide group, are present. The unprecedented highly regioselective attack of the alkylating agent onto the neutral pyridic nitrogen rather than the highly charged carbanionic carbon has been also confirmed in the case of the intermolecular competition. Multinuclear (13C and 15N) NMR spectroscopy has been used to investigate the structure and the extent of intramolecular charge transfer in 1, which are shown to exist in the ground state as highly charge-separated zwitterionic systems. Experimental results are discussed and compared with semiempirical (PM3) computations. The solvatochromic response of compounds 1, among the highest ever reported in the literature for similar systems, candidates this class of compounds as very attractive active components of nonlinear optical materials.
