New luminescent dinuclear rhenium(I) tricarbonyl complex-PNA conjugates have been synthesized through a reliable solid-phase synthetic methodology. Their photophysical properties have been measured. The most luminescent Re-PNA conjugate 7 showed interesting two-photon absorption (TPA) properties, that were exploited for imaging experiments, to demonstrate its easy uptake into living cells.

We report here a luminescent metal-organic framework [Zn3(TDPAT)(H2O)3] [TDPAT = 2,4,6-tris(3,5-dicarboxyl phenylamino)-1,3,5-triazine] exhibiting strong luminescence at room temperature, which can serve as the first case of a dual functional luminescent sensor for quantitatively detecting the concentration of nitrobenzene and temperature.

We report herein the mechanochromic luminescent property of a dendritic polypeptide with a fluorescent aromatic moiety at the focal point. The different luminescent property of 1 under mechanical stimulus is attributed to the switch of self-assembled structures. Moreover, the photoluminescence property of 1 also depends on the thermal history.

Oxygen-deficient luminescent mesoporous silica nanoparticles with uniform morphology/size and integrated mesoporosity-luminescent property in a single nanoparticle are successfully synthesized by a bottom-up self-assembly route followed by a post-calcination process, and can be used to facilely load/deliver drugs into cells and luminescently image cells.

A simple strategy has been developed to synthesize highly luminescent thiolated Au@Ag nanoclusters (NCs) by using Ag(i) ions to bridge small Au(i)-thiolate motifs on the weakly luminescent thiolated Au NCs, leading to the formation of large Au(i)/Ag(i)-thiolate motifs on the NC surface and thus generating strong luminescence via aggregation-induced emission.

In this paper, preparation of SrAl2O4:Eu,Dy luminescent pigment has been investigated. Coprecipitation as a low cost and facile method was selected. X-ray diffraction patterns indicated the formation of SrAl2O4:Eu,Dy phase through calcinations process above 800 °C. Moreover, a few amount of silica caused the structural transformation to alumina silicate phase. Transparent glaze which consist of...

Metal-organic frameworks (MOFs) are a rapidly growing class of hybrid materials with many multifunctional properties. The permanent porosity plays a central role in the functional properties. In particular, the luminescent MOFs with a permanent porosity have wide applications in guest species recognition and adsorption. In this contribution, we aim to develop tunable colors and white-light lumi...

Highly scattering plasma-sprayed thermal barrier coatings (TBCs) present a challenge for optical diagnostic methods to monitor TBC delamination because scattering attenuates light transmitted through the TBC and usually degrades contrast between attached and delaminated regions of the TBC. This paper presents a new approach where reflectance-enhanced luminescence from a luminescent sublayer inc...

Stimulation-responsive luminescent materials have attractd intense attention due to their excellent optical properties in the anticounterfeiting application. At present, most are based on single luminescence and fixed excitation patterns, resulting a poor effect. Therefore, developing multimodal that change luminous color under different wavelength stimuli has become significant challenge. In t...
