Multi-disciplinary research programs involving organic synthesis, molecular recognition, fluorescent sensing, asymmetric catalysis, and polymers are conducted in our laboratory.  The 1,1′-bi-2-naphthol (BINOL) and its derivatives are chosen as the chiral building blocks to construct novel chiral molecules and macromolecules for diverse applications.  We have developed a family of enantioselective fluorescent sensors for the recognition of organic molecules such as alpha-hydroxycarboxylic acids, amino acids, amino alcohols, and amines.  These sensors are potentially useful for rapid assay of the enantiomeric composition of chiral compounds and for high throughput chiral catalyst screening.  They are also potentially useful for biological analysis and imaging.  New chiral conjugated polymers and dendrimers are prepared for applications in materials, catalysis, and sensing.  We have discovered that the Lewis acid complexes of the optically active binaphthyl molecules and polymers can carry out highly enantioselective organic reactions such as organozinc additions to aldehydes, hetero-Diels-Alder reactions, 1,3-dipolar cycloadditions, reductions of ketones, Michael additions, epoxidations, and others.  Interesting chiral organic molecules including those of biological functions are prepared by using these catalysts.
