A novel microporous organic material [(2-{2-[2-(bis- methoxycarbonylmethylamino)phenoxy] ethoxy}-4-benzimidazole-phenyl) methoxycarbonylmethylamino]acetic acid methyl ester 6 was synthesized and characterized by single crystal X-ray diffraction, Fourier transform infrared spectroscopy (FT-IR), electron spray ionization-mass spectrometry (ESI-HRMS), X-ray powder diffraction (PXRD), 1H and 13C NMR. 6 crystallizes in the centrosymmetric monoclinic space group C2/c, with unit cell parameters a = 35.648(3) A?, b = 14.3240(12) A?, c = 15.3693(13) A?, α = 90.00, β = 94.8190(10),. = 90.00, V = 7820.16 A?3 and Z = 8 at 296(2) K. As indicated by crystal packing, the molecular conjugation planes arrange along the c axis to form micropores due to the hydrogen bonds. In addition, the fluorescent spectrum and luminescence lifetime were studied for 6.

We introduce a selective and cell-permeable calcium sensor for photoacoustics (CaSPA), a versatile imaging technique that allows for fast volumetric mapping of photoabsorbing molecules with deep tissue penetration. To optimize for Ca2+-dependen

We report a two-photon (TP) probe (ACaLN) for near-membrane Ca2+ that shows a 13-fold TP excited fluorescence (TPEF) enhancement in response to Ca2+, dissociation constants (KdTP) of (1.9±0.2) μM, pH-insensitivity at the biologically relevant pH, and can detect near-membrane Ca2+ in live cells for more than 1500 s and in living tissues at 120 μm depth without interference from other metal ions. Comparison with existing probes provides a useful strategy for the design of efficient TP probes for the near-membrane metal ions.
