    offer By virtue of their attractive characteristics for electro optic applications ferroelectric liquid crystals FLCs are poised for wide commercial applications and the LC MRC has aggressively pursued its role as the principal US resource for FLC industrial development doing collaborative research with a variety of companies Although the principal worldwide focus of LC research is on applications liquid crystals also present a variety of challenging problems and opportunities for advancing the basic science of liquid crystals Surely one of the most exciting and challenging areas of condensed matter physics is understanding the connection between molecular and macroscopic properties of organic materials LCs by virtue of the undeniably intimate coupling of their distinctive molecular architectures and macroscopic properties are a fruitful testing ground for studying this connection For example the polarization in FLCs is one of the most direct and experimentally accessible probes of orientational ordering in liquid crystals Chiral LCs remain at the frontier of liquid crystal science surprising us with unexpected phases structures fluctuations interface behavior and optical effects We understand little of LC molecular macroscopic relations making the directed design of LCs more of an art than a science LCs offer unique opportunities for improving our understanding of condensed matter The purpose of the LC MRC is to create a context in which these problems can be effectively addressed The LC MRC vertically integrates LC chemical synthesis materials evaluation and molecular modeling in a coherent research program directed toward broadening our basic scientific understanding of molecular ordering in liquid crystals and toward developing new LCs for EO NLO and other novel applications Noel A Clark Principal Investigator Professor Department of Physics University of Colorado Boulder CO 80309 David M Walba Co Principal Investigator Professor Department of Chemistry and Biochemistry University of Colorado Boulder CO 80309 Matthew A

    in this application 1 Obtaining adequately large EEO second order susceptibility coefficients r 50 pm V and 2 Optical quality The former goal is being addressed both empirically and by employing LC design tools for pre synthesis assessment of the orientational ordering of FLC molecules containing carefully chosen highly nonlinear chromophores suitable for use in EEO with 1 3 micron light The latter goal is being addressed by developing a better understanding of FLC alignment Computational Tools for LC Materials Design and Discovery The microscopic behavior of LC systems remains poorly understood at a fundamental level as does the emergence of macroscopic properties from their collective behavior Center research focuses on the application of computer simulation and statistical mechanics to the development of a molecular level understanding of self organization in liquid crystalline materials and on the creation of calculational tools for the directed design and pre synthesis prediction of LC properties from chemical structure This broad based research effort requires an equally broad range of calculational approaches a modeling hierarchy including computationally inexpensive single molecule mean field theory based methods intermediate scale pair or cluster approximations and exploratory large scale atomistic simulations We have applied this hierarchical strategy in the creation of predictive mean field models of FLC polarization and other properties and in pioneering large scale simulation studies of LC microphysics We are pursuing the wider application of mean field theory and large scale simulation to the calculation of critical materials properties of LCs and to a baseline microscopic characterization of LC phases We plan to extend our computational capabilities through the creation of intermediate scale calculational approaches including cluster simulation methods for modeling small numbers of molecules with appropriately designed mean field boundary conditions and application of liquid state theory and density functional theory to the calculation
