Supramolecular Micro-/Nano- Wires for Integrated Nonlinear Optics

Samenvatting

Since the advent of the laser and the subsequent discovery of nonlinear optics (NLO), there has been an untiring search for novel NLO materials. Subwavelength micro-/nano- wire-like structures are of critical importance as building blocks for light generation, propagation, amplification, and modulation, for the next generations of integrated optical circuits. Currently, most photonic components are based on inorganic nonlinear optical materials, though organic materials intrinsically have higher hyperpolarizabilities, come with diverse architectures, and show very fast NLO responses. The challenge for organic NLO materials lies in the use of weak noncovalent interactions between the organic molecules to construct suitable and stable organizations for generating NLO effects, in particular second-order ones for which non-centrosymmetric arrangements are essential. In this proposal, I intend to pursue a supramolecular approach for the construction of organic based multi-responsive NLO micro-/nano- wire materials, with a final goal to obtain new designing parameters for superior organic photonic materials.

Supramolecular Chemistry can be summarized by the combination of complementary nonconvalent interactions with a ?1+1>2? amplification. In my proposal, the synergistical action of the tailor-made building blocks (fluorenone analogues, peptides) are employed as driving forces to construct macroscopically dipolar supramolecular systems, for generating second-order NLO. Moreover, these bottom-up supramolecularly engineered systems will afford micro-/nano- scale chromophoric arrays with additional functionalities, leading to multi-responsive materials. Their NLO responses as well as the dynamics will be investigated by an integrated approach ultilizing tailor-made molecular and supramolecular synthesis, theoretical simulations, and ultrafast laser technologies. Very importantly, the relationships between the NLO properties and the (supra)molecular architectures will be correlated, with my final goal to obtain first principle designing parameters to guide future exploitations of organic NLO materials. The potential applications of the micr-/nano- mires as optical building blocks for waveguiding, microcavity lasing, and laser modulation will be studied.
