Abstract:

The highly stereoregular preparation of mono-substituted polyacetylenes (SPA)s was performed using an [Rh(norbornadiene)Cl]2-triethylamine catalyst to give the π-conjugated helical polymers. Because the SPAs are expected as new advanced materials due to semiconductivity, NLO properties, external stimulus responsibility, enantioselectivity, and oxygen permeability. These properties are strongly related to the geometrical structure, e.g., cis or trans forms and higher-order structure, e.g., p stacking along with the helical main-chain in the solid phase. Therefore, we have investigated whether the geometrical and helical structures of the SPAs can be controlled through molecular design and/or external stimuli. The p-n-hexyloxyphenylacetylene (pPA) monomer was stereoregularly polymerized using the Rh catalyst at 25 °C. When ethanol and n-hexane were used as the polymerization solvents, a yellow P(Y), and its red P(R) were obtained, respectively. The diffuse reflective UV-vis spectra of these polymers showed lmax at 445 and 575 nm, respectively. The WAXS patterns of P(Y) and P(R) exhibited hexagonal columnar structures which were attributed to the stretched and contracted helices, respectively. Additionally, P(Y) was irreversibly transformed into a reddish-black P(YB), whose columnar diameter was identical to that of P(R) when heated at 80 °C for 1 h. These findings suggest a thermally irreversible rearrangement from a thermally unstable P(Y) with a stretched helix to a stable P(YB) with a contracted helix. In the case of aliphatic polyacetylene ester the mutual helical oscillation between the contacted and stretched helices was found in the solution1

Abstract:

Catalytic decontamination of water by solar energy has attracted substantial interest over the past decades. However to develop an efficient photocatalyst for such environmental purification, in particular water treatment still remains a big challenge, involving Material Science, Chemistry, Engineering and Physics. In particular there is not a cost effective way to deal with large volume of water contaminated by small amount of organic substance or extreme large amount of contaminated water in suburban region (e.g. oil spill in Mexico Gulf, in China Bohai Sea).

 

Inorganic photocatalysis using solar energy to mineralize organic contaminants in principal is the potentially best solution to these issues and works in the cost effective way. Recently we preliminarily illustrated the key factors dominating the efficiency of process driven by light irradiation.1 Following that, water treatment was carried out in my group which is a challenging topic due to its complexity. In this talk, the mechanism of the chemical process, involving charge transfer and reaction with oxygen, will be addressed and structured/junction material development will be presented, resulting into a few times higher activity for textile water treatment2,3  and simulated river water treatment4,5 compared with the benchmark photocatalyst P25. Furthermore, a new and facile method to synthesize these active photocatalysts will be discussed
