Self-Assembly of Bridged Silsesquioxanes: Modulating Structural Evolution via Cooperative Covalent and Non-covalent Interactions 
Auteur(s): Creff Gaëlle, Pichon Benoît P., BLANC C., MAURIN D., SAUVAJOL J.-L., Carcel Carole, Moreau Joël, Roy Pascale, Bartlett John R., Wong Chi Man Michel , BANTIGNIES J.-L.

DOI: 10.1021/la400293k
Résumé: The self-assembly of a bis-urea phenylene-bridged silsesquioxane precursor during sol-gel synthesis has been investigated by in situ infrared spectroscopy, optical microscopy and light scattering. In particular, the evolution of the system as a function of processing time was correlated with covalent interactions associated with increasing polycondensation and non-covalent interactions such as hydrogen bonding. A comprehensive mechanism based on the hydrolysis of the phenylene-bridged organosilane precursor prior to the crystallization of the corresponding bridged silsesquioxane via H bonding and subsequent irreversible polycondensation is proposed.

New Insights on Vibrational Dynamics of Corannulene 
Auteur(s): LE PARC R., Hermet P., Rols Stephane, MAURIN D., ALVAREZ L., Ivanov Alexandre, Quimby Jennifer m., Hanley Caitlin g., Scott Lawrence T., BANTIGNIES J.-L.
(Article) Publié:
The Journal of Physical Chemistry C, vol. 116 p.25089-25096 (2012)
Ref HAL: hal-00811653_v1
DOI: 10.1021/jp307536d
Résumé: Vibrational dynamics in the corannulene crystal is exhaustively studied through Raman scattering, infrared spectroscopy, and inelastic neutron scattering. Experimental data are coupled to simulations of the phonon modes performed in the framework of first principle calculations. Intermolecular vibrations (libration and translation) are assigned in the low frequency domain (10-200 cm-1). These modes exhibit specific temperature dependence in the far-infrared.

Investigation on the vibrational and structural properties of a self-structured bridged silsesquioxane 
Auteur(s): Greff Gaëlle, Arrachart Guilhem, HERMET P., Wadepohl Hubert, Almairac Robert, MAURIN D., SAUVAJOL J.-L., Carcel Carole, Moreau Joël J.E., DIEUDONNÉ P., Wong Chi Man Michel, BANTIGNIES J.-L.

Physical Chemistry Chemical Physics, vol. 14 p.5672-5679 (2012)
Ref HAL: hal-00683723_v1
DOI: 10.1039/c2cp40250e
Résumé: The crystalline structure of ureidopyrimidinone-based silane (UPY) has been determined. The local and long range order structuring of the bridged silsesquioxane (MUPY) resulting from the sol-gel hydrolysis-condensation of the former precursor has been investigated by MFTIR (Mid Fourier Transform InfraRed) combined with DFT (Density Functional Theory) and XRD (X-ray diffraction) studies. These studies showed that a long range structuring exists within the organic fragments with the transcription of the DDAA (Donor-Donor-Acceptor-Acceptor) H-bonding array from UPY to MUPY whereas a disordered siloxane network was revealed in the hybrid material.
