Solvent-induced multicolour fluorescence of amino-substituted 2,3-naphthalimides studied by fluorescence and transient absorption measurements

A series of amino-2,3-naphthalimide derivatives having the amino functionality at 1-, 5- and 6-positions (1ANI, 5ANI and 6ANI, respectively) were prepared, and their photophysical properties were systematically investigated based on the measurements of st

A highly rigid and gas selective methanopentacene-based polymer of intrinsic microporosity derived from Tr?ger's base polymerization

Polymers of intrinsic microporosity (PIMs) have been identified as potential next generation membrane materials for the separation of gas mixtures of industrial and environmental relevance. Based on the exceptionally rigid methanopentacene (MP) structural unit, a Polymer of Intrinsic Microporosity (PIM-MP-TB) was designed to demonstrate high selectivity for gas separations. PIM-MP-TB was prepared using a polymerisation reaction involving the formation of Tr?ger's base linking groups and demonstrated an apparent BET surface area of 743 m2 g-1 as a powder. The microporosity of PIM-MP-TB was also characterized by chain packing simulations. PIM-MP-TB proved soluble in chlorinated solvents and was cast as a robust, free-standing film suitable for gas permeation measurements. Despite lower gas permeability as compared to previously reported PIMs, high selectivities for industrially relevant gas pairs were obtained, surpassing the 2008 Robeson upper bound for H2/CH4 and O2/N2, (e.g., PO2 = 999 Barrer; αO2/N2 = 5.0) and demonstrating a clear link between polymer rigidity and selectivity. Upon aging, the permeability data move parallel to the Robeson upper bounds with a decrease of permeability, compensated by a related increase in selectivity. Mixed gas permeation measurement for CO2/CH4 and CO2/N2 mixtures confirmed the excellent selectivity of PIM-MP-TB for potentially relevant separations such as biogas upgrading and CO2 capture from flue gas. Importantly, unlike other high performing PIMs, PIM-MP-TB is prepared in four simple steps from a cheap starting material.

Unusual large Stokes shift and solvatochromic fluorophore: Synthesis, spectra, and solvent effect of 6-substituted 2,3-naphthalimide

In this article, four new series of 6-substituted 2,3-naphthalimides (1a-d, 2a-d, 3a-d, 4a-d and 4 e-h) have been designed and synthesized through the formation of key cyclic anhydride intermediate, which was the precursor of the well known environment-sensitive fluorophore [6-N,N-dimethylaminonaphthalimides (6-DMN)] and other 6-substituted 2,3-naphthalimide series (2, 3, 4). Based on 6-amino-2,3-naphthalimide (6-ANP) compound, a new type of fluorophore was found to exhibit moderate to unusual large Stokes shift (297-303 nm). 6-ANP derivatives display relatively low fluorescence quantum yields in high polar protic solvents such as water (ΦF ～ 0.004, 571-576 nm) and a significant unusual red shift due to (1) hydrogen bonding interaction of the excited state of the molecule with the solvents, which presumably enhance the intersystem crossing process in the system to quench fluorescence, (2) this large Stokes shift was assumed to be the consequence of a substantial change of the geometric structure from the ground state (S0) to the first excited state (S1). Compared with the other compounds studied, the fluorescence of the nitro- and halo-derivatives was rather weak, probably due to the efficient intersystem crossing leading to a non-reactive triplet state.
