Reference excerpt

Tris(8-hydroxyquinolinato)aluminium is the chemical compound with the formula Al(C9H6NO)3. Widely abbreviated Alq3, it is a coordination complex wherein aluminium is bonded in a bidentate manner to the conjugate base of three 8-hydroxyquinoline ligands.

Structure Both the meridional and facial isomers are known as well as several polymorphs (different crystalline forms).

Synthesis The compound is prepared by the reaction of 8-hydroxyquinoline with aluminium(III) sources

Al3+ + 3 C9H7NO → Al(C9H6NO)3 + 3 H+ The synthesis and precipitation are so efficient that this reaction is used in gravimetric analysis for aluminium.

Applications Alq3 is a common component of organic light-emitting diodes (OLEDs). Variations in the substituents on the quinoline rings affect its luminescence properties.

Worked examples

Example 1 — a first encounter with Tris(8-hydroxyquinolinato)aluminium

Start with the simplest possible case. Write down what Tris(8-hydroxyquinolinato)aluminium claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tris(8-hydroxyquinolinato)aluminium before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tris(8-hydroxyquinolinato)aluminium ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tris(8-hydroxyquinolinato)aluminium

In research: Tris(8-hydroxyquinolinato)aluminium appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tris(8-hydroxyquinolinato)aluminium in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tris(8-hydroxyquinolinato)aluminium is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aluminium compounds, Coordination complexes, Quinolinols, so understanding it makes those chapters shorter.
In everyday life: Look for Tris(8-hydroxyquinolinato)aluminium outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
