A Luminescent Metal-Organic Framework Thermometer with Intrinsic Dual Emission from Organic Lumophores.

A new mixed-ligand metal-organic framework (MOF), ZnATZ-BTB, has been constructed as a luminescent ratiometric thermometer by making use of the intrinsic dual emission at cryogenic temperatures. Its twofold interpenetrated network promotes the Dexter energy transfer (DET) between the mixed organic lumophores. The temperature-dependent luminescent behavior arises from the thermal equilibrium between two separated excited states coupled by DET, which is confirmed by Boltzmann distribution fitting.

Comparative analysis of complete chloroplast genome sequences of two tropical trees Machilus yunnanensis and Machilus balansae in the family Lauraceae.

Machilus is a large (c. 100 sp.) genus of trees in the family Lauraceae, distributed in tropical and subtropical East Asia.

Implementation of Arithmetic Functions on a Simple and Universal Molecular Beacon Platform.

are fabricated to implement arithmetic functions based on a simple and single molecular beacon platform, including half adder, half subtractor, full adder, full subtractor, and a digital comparator. Dual fluorescence outputs are generated in parallel and a constant threshold value is set to build all the logic circuits. The developed enzyme-free DNA system provides a novel prototype for the design of high-level molecular logic circuits on a biomolecular platform.

Solution-processable carbazole-based conjugated dendritic hosts for power-efficient blue-electrophosphorescent devices.

A novel class of hosts suitable for solution processing has been developed based on a conjugated dendritic scaffold. By increasing the dendron generation, the highest occupied molecular orbital (HOMO) energy level can be tuned to facilitate hole injection, while the triplet energy remains at a high level, sufficient to host high-energy-triplet emitters. A power-efficient blue-electrophosphorescent device based on H2 is presented.

Intrinsically organized network for face perception during the resting state.

We investigated 0.01-0.08Hz low-frequency fluctuations of BOLD-fMRI signals in the face and object-responsive regions during the resting-state and during face or object viewing tasks.
