标题 :Convergent synthesis of multiporphyrin light-harvesting rods
发明人：LINDSEY JONATHAN S; LOEWE ROBERT S
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides a convergent method for the synthesis of light harvesting rods. The rods are oligomers of the formula A 1 (A b+1 ) b , wherein b is at least 1, A 1 through A b+1 are covalently coupled rod segments, and each rod segment A 1 through A 1+b comprises a compound of the formula X 1 (X m+1 ) m wherein m is at least 1 and X 1 through X m+1 are covalently coupled porphyrinic macrocycles. Light harvesting arrays and solar cells containing such light harvesting rods are also described, along with intermediates useful in such methods and rods produced by such methods.

标题 :System for multiple simultaneous synthesis
发明人：DEWITT SHEILA H H; KIELY JOHN S; PAVIA MICHAEL R; SCHROEDER MEL C; STANKOVIC CHARLES J
权利人:WARNER LAMBERT CO
摘要:A system for the multiple, simultaneous synthesis of compounds preferably uses a reaction apparatus comprising a reservoir rack having a plurality of reaction wells, a plurality of reaction tubes, usually gas dispersion tubes, having filters on their lower ends, a holder block, having a plurality of apertures, and a manifold, which has ports to allow introduction/maintenance of a controlled environment. The manifold top wall has a plurality of apertures in axial alignment with the reaction tubes and a gasket which allows penetration by a needle in order to dispense and aspirate materials from the reaction tubes. Sealing members, such as gaskets, are placed between the holder block, manifold and reservoir rack and the components are releasably fastened together. A robotic sample processor is used to automate the synthesis process using the reaction apparatus.
