Double carbohelicenes have attracted considerable attention due to their aesthetic structures, distinct π-conjugation extension, inherent chirality, and intriguing optical and electronic properties. Herein, the concise de novo synthesis of a new double[5]carbohelicene 1 together with its chiroptical properties, isomerization process and lasing application is presented. 1 was synthesized by a simple protocol involving the formation of a 6,6′-bipentacene as the key intermediate. It is worth noting that1 existed as two diastereomers 1-PP/MM and 1-PM, which were successfully isolated and unambiguously confirmed by Xray crystallography. The optical resolution of the racemic 1-PP/MM was successfully achieved by chiral-phase highperformance liquid chromatography（HPLC）, and 1-PP and 1-MM were characterized by circular dichroism. Interestingly, it was found that 1-PP/MM could be completely isomerized to 1-PM upon heating, and the detailed thermodynamics and kinetics of the isomerization process were systematically investigated. 1-PM exhibited deep-red luminescence with emission maximum at 723 nm and fluorescence quantum yield as high as 32.95%. Consequently, we can showcase the lasing application of 1-PM by doping with epoxy resin to assemble a bottle microlaser spontaneously, which the lasing wavelength is 796.6 nm at a threshold of 0.8 m J cm-2. We believe that our studies, including the facile synthesis methodology, detailed isomerization studies, and lasing application, will shed some light on the design and synthesis of novel carbohelical systems with more functions.

Background Local failure of nasopharyngeal carcinoma （NPC） after radiotherapy （RT） remains one of the major treatment failures. This study aimed to evaluate the clinical efficacy and complications of fractionated stereotactic radiotherapy （FSRT） with vagina carotica protection technique for local residual of NPC patients after the primary RT. Methods From August 2006 to August 2010, FSRT with vagina carotica protection technique was applied to 36 patients in our department, the patients aged between 13 and 76 years with a median of 41.3 years, 25 of them were male and 11 were female. According to 2002 Union for International Cancer Control （UICC） Staging System, the stages before primary radiotherapy were： Ila 2, lib 5, III 18, IVa 7, IVb 4. In the first course of radiotherapy, 9 patients received conventional RT, 27 patients received intensity modulated radiotherapy （IMRT） and 20 out of the 36 patients received concurrent chemoradiotherapy. The total dose in the first course of RT was 69.96-76.90 Gy （median, 72.58 Gy）. The intervals between the primary RT and FSRT ranged from 12 to 147 days （median, 39.8 days）. Target volumes ranged from 1.46 to 32.98 cm3 （median, 14.94 cm3）. The total FSRT doses were 10.0-24.0 Gy （median, 16.5 Gy） with 2.0-5.0 Gy per fraction. The most common regimen was 15 Gy in 5 fractions of 3 Gy, the irradiation dose to vagina carotica was less than 2 Gy per fraction. Results The median follow-up time was 34 months （range, 12-59 months）. The 3-year local control rate was 100%; the 3-year overall survival rate was 94.4%; the 3-year disease-free survival rate was 77.8%. In this study, we had one case of cranial nerve injury, two cases of temporal lobe necrosis, and no nasopharyngeal massive hemorrhage was observed. Conclusion FSRT with vagina carotica protection technique is an effective and safe RT regimen for local residual of NPC with reduction of radiation-related neurovascular lesions.

Studying molecular recognition in aqueous environments is crucial for understanding biological processes. Herein, we present a series of N-doped endo-functionalized anthracene-based cavities by introducing inward-directed pyridine units. The subtle modifications can significantly affect the binding properties of these receptors, which is similar to the mutations in biological systems. Combining theoretical calculations and molecular recognition experiments demonstrated that these “mutations” have an impact on the hydrophobicity and charge distribution of the hosts, consequently significantly influencing molecular *** is crucial for understanding the intricate mechanisms of molecular-level interactions in biological receptors.

In recent years, large-area wide-bandgap (WBG) semiconductor materials have achieved numerous notable breakthroughs [1, 2]. The ultra-WBG semiconductor β-Ga2O3,with its excellent material properties, is ideally suited for the fabrication of power devices. Moreover, it offers easily obtainable large-area substrates, with reported sizes up to 6 inches, produced through melt-grown crystal growth methods. These characteristics make β-Ga2O3 highly attractive for future low-cost commercialization. Despite these advances, most research has focused on low-current and small-size diodes, with few studies addressing high-current and large-size diodes.
