D-A charge transfer, including through-bond charge transfer and through-space charge transfer between two different electron donors(D) and electron acceptors(A), is a fundamental and powerful tool to tune the optical properties of organic dyes. Herein,we demonstrate a unique strategy to tune phosphorescence and circularly polarized luminescence properties of axially chiral binuclear Pt(Ⅱ) complexes through long-range charge transfer, even though these molecules have two totally identical segments on either side of the chiral core. The presence of axial chirality would break not only the symmetry of molecular structure and π-conjugation system but also the symmetry of charge distribution for long-range charge transfer. These binaphthyl-based Pt(Ⅱ)complexes bearing coordinated atoms far away from chiral axis exhibit no Pt-Pt interactions but colorful concentrationdependent phosphorescence with quantum yield up to 86.4% and could be applied as emitters in highly efficient solutionprocessed organic light-emitting diodes to achieve luminance, luminance efficiency, power efficiency, external quantum efficiency, and asymmetry factor up to 8.94 × 10^(3)cd m^(-2), 41.9 cd A-1, 18.8 lm W^(-1), 12.6% and 2.98 × 10^(-3), respectively. Therefore,the present work affords a new and simple way to utilize the inherently asymmetric advantage of chirality for the design of D-Abased organic dyes.

BACKGROUND Pregnancy in the setting of systemic lupus erythematosus can worsen thecondition from the stable to active stage, with quality of life and fertility desirebeing particular concerns. Pregnancy in the active stage of systemic lupuserythematosus (ASLE), although rare and complicated to manage, can be treatedfavorably with immunotherapies ifs used properly. Here we report such a *** SUMMARY A 31-year-old primigravida patient, diagnosed with SLE seven years ago, wasinduced ASLE after a cold at 21 + weeks. The patient’s vital signs on presentationwere normal. Her laboratory exam was remarkable for significant proteinuria,liver and renal dysfunction, and low C3 and C4 levels. Infectious work-up wasnegative. The patient was diagnosed with ASLE. She was given immunosuppressiveagents (methylprednisolone, gamma globulin and azathioprine etc.)and plasma adsorption therapy, monitoring blood pressure every 8 h, fetal heartrate twice a day, and liver and renal function at least twice a week. Successfulmaternal and fetal outcomes are presented *** Child-bearing in ASLE has become more promising, even for this difficult case ofASLE with multiple organ damage. Thorough antepartum counseling, cautiousmaternal-fetal monitoring, and multi-organ function monitoring bymultidisciplinary specialties are keys to favorable pregnancy outcomes.

In this paper, the hydrodynamic coefficients of a horizontal semi-immersed cylinder in steady current and oscillatory flow combining with constant current are obtained via forced oscillation experiments in a towing tank. Three nondimensional parameters(Re, KC and Fr) are introduced to investigate their effects on the hydrodynamic *** experimental results show that overtopping is evident and dominates when the Reynolds number exceeds 5×105 in the experiment. Under steady current condition, overtopping increases the drag coefficient significantly at high Reynolds numbers. Under oscillatory flow with constant current condition, the added mass coefficient can even reach a maximum value about 3.5 due to overtopping while the influence of overtopping on the drag coefficient is minor.
