Case Study

Dimethylgermanium Dichloride for The Synthesis of Germole-Containing π-Conjugated Polymer

Zheng, Feng, et al. NPG Asia Materials, 2020, 12(1), 41.

A germole-containing π-conjugated polymer was prepared by reacting a lithiated polymer precursor with dimethylgermanium dichloride. The polymer exhibited green photoluminescence in chloroform solution and could be employed as a fluoride chemical detector.
A regioregular organometallic polymer featuring 1,4-dilithio-1,3-butadiene and 9,9-dioctylfluorene-2,7-diyl units was synthesized by reacting a tellurophene-containing polymer, which had a number-average molecular weight (Mn) of 5900 and a molecular weight distribution (Mw/Mn) of 1.9, with n-butyllithium (2.4 equivalents) at temperatures ranging from -78 to -60 °C for 3 hours.
The resulting lithiated polymer was then treated with dimethylgermanium dichloride (1.5 equivalents) at -60 °C, allowing the reaction to proceed to ambient temperature over 12 hours in tetrahydrofuran, yielding a π-conjugated polymer containing 1,1-dimethylgermole-2,5-diyl units with a 76% yield (Mn = 4400 and Mw/Mn = 1.7).

Dimethylgermanium Dichloride for Preparation of Germanium-Containing Polyalkylsiloxane Gas Separation Membrane

Borisov, Ilya L., et al. Key Engineering Materials, 2020, 869, 45-50.

A germanium-containing polyalkylsiloxane was synthesized by polycondensation reaction using dimethylgermanium dichloride as raw material, and then a new high-permeability membrane with high selectivity for butane/methane was obtained by cross-linking with TEOS.
Synthesis of germanium-containing polyalkylsiloxane membrane
· The synthesis of 1,1,3,3,5,5-hexamethyl-1,5-dihydro-3-germyl-1,5-disilapentane was accomplished in a single reaction mixture, involving the intermediate formation of a Grignard reagent that reacts with dimethylgermanium dichloride. This method leveraged the increased reactivity of Grignard reagents derived from chloromethyl silicon compounds with the CH2-Cl bond, following a Wurtz-type reaction.
· The polycondensation reaction was employed to synthesize a new polycarbosiloxane featuring a germanium atom in the gem-position. The precursor, 1,1,3,3,5,5-hexamethyl-1,5-dihydro-3-germyl-1,5-disilapentane (I), was mixed with its ethoxy derivative (1,1,3,3,5,5-hexamethyl-1,5-diethoxy-3-germyl-1,5-disilapentane (II)), and in the presence of a catalyst (a boron complex with hexafluorobenzene), polycondensation occurred, releasing ethane and yielding products with a molecular weight between 50,000 and 15,000 g/mol.
· Dimethyltindinodecanoate was the crosslinking agent, added at a level of 0.2% by weight of the polymer. Membranes made of the produced polycarbosiloxane with the germanium atom were formulated by pouring a toluene solution on to a stainless steel mesh (mesh size 40 m). The membranes were poured, left to dry at 60 °C for 24 hours and vacuum dried at 60 °C for another 24 hours before removal of solvent. The net thickness of membranes subsequently calculated was between 70 and 80 μm.
