摘要：

At 77 K in the solid state and in ethanol glasses, o-carborane (1,2-C(2)B(10)H(12)) shows a relatively intense (phi similar to 10(-3) at lambda(exc) = 260 nm) structured photoluminescence (lambda(max) = 441 nm). In agreement with the rather slow decay of this emission (iota similar to 4 s) it is suggested to be a phosphorescence. While it appears to be a genuine property of o-carborane an unknown impurity as origin of this luminescence is not completely excluded. (C) 2004 Elsevier B.V. All rights reserved.
