Methanol → Bis(trihexylsiloxy)silicon 2,3-naph- thalocyanine

Participants

Reaction Steps

A mixture of tri-n-hexylsilanol (14.9 g), sodium methoxide (2.67 g) and absolute ethanol (50 ml) was reduced to an oil under vacuum. This oil was added to a mixture of dichlorosilicon phthalocyanine (Formula 9, from Aldrich Chemical CO., Milwaukee, Wis., 15.10 g) and distilled, dry 1,2,4-trimethyl-benzene (70 ml). The resulting suspension was refluxed for 1 hr and was filtered hot using Whatman #54 filter paper. The filtrate was allowed to cool (12 hr) and was diluted with methanol (350 mol). The precipitated product of Formula 10 was isolated by filtration, washed with methanol (100 ml) and vacuum dried at room temperature overnight, (22.06 g, 79% yield) m.pt. 175° C.; IR (Nujol) 1525 (s), 1325 (s), 1125(s), 1080 (s), 1038 (s, Si--O--Si), 725 (s) cm-1.
