  abstract     = {{Tetraethyl orthosilicate (TEOS) directly electrospun nanofibrous membranes are well-established for high-demanding applications. However, further expansion and exploitation of these materials require broadening the portfolio of Si-based precursors. In the present work, a part of the Si–O–Si linkages is therefore replaced by terminal groups (Si–R) or bridged organic linkages (Si-R-Si), playing with the inorganic-organic precursor balance considering triethoxymethylsilane (TEOMS), bis(triethoxysilyl)methane (BTESM) or bis(triethoxysilyl)ethane (BTESE). Both a rheological and kinetic analysis for the sol-gel synthesis of these three precursors is first done in comparison with the TEOS-based reference system, followed by an in-depth study of the electrospinning potential and the resulting organosilica nanofibrous materials properties. The production of the nanofibrous materials is achieved by electrospinning of a partly cross-linked sol-gel system with an optimal initial precursor/H2O/EtOH ratio selecting a sufficiently low temperature. It is demonstrated that the precursor/H2O ratio mainly controls the reactivity of the polycondensation by hydrolysis enhancement, and the precursor/EtOH ratio allows control over the dynamic viscosity due to dilution of the system. Depending on the chemical structure, a different range of workable viscosity conditions is obtained, highlighting the relevance of the construction of structure-property relationships. The rheological and kinetic analysis underpinned the relation of chemistry building blocks and organosilica network synthesis for material applications in general for the first time. Overall, a wide portfolio of membrane properties is reported, including the control over water take-up, acidity and basicity strength, and thermal stability starting from molecular thus chemical variations.}},
